Why is it not possible to add the Altera® LDPC IP to designs targeting Cyclone® IV E FPGA devices? - Why is it not possible to add the Altera® LDPC IP to designs targeting Cyclone® IV E FPGA devices? Description Due to a problem in the Altera® LDPC IP Core User Guide, it is incorrectly stated that the Cyclone® IV FPGA device family is supported. The Altera® LDPC IP is not supported on Cyclone® IV E FPGA devices. Resolution The Altera® LDPC IP is part of a product obsolescence and support discontinuation schedule. For the schedule, refer to the Product Discontinuation Notice PDN2208 . For new designs, Altera recommends that you use other IPs with equivalent functions. To see a list of available IPs, refer to the Altera® FPGA Intellectual Property webpage.
